For small surface rust repair what's the best method? My Dart has small spots from rock chips over the years. I don't want to cut a solid rocker out for a small amount of surface rust. Yet I am scared it will come back thru the new paint. What's the best method grinding it out and then acid etch primer and metal glaze over the acid etch primer???
